TIRE-ROLLING MILL.
Specification of ietters Patent. Patented M 22 1921 Application filed November 6, 1919. Serial No. 336,119.
- for rolling blanks having a central opening,
into rings or tires, or into a ring shaped billet adapted to be cut and straightened and rolled in rails, and it consists in the parts and combination of parts as will be more fully explained and pointed out in the claims.
In the accompanying drawings Figure 1 is a view in vertical section of my improved mill; Fig. 2 is a similar view of a part of the same showing the rollers se arated; Fig. 3 is a view in plan and Fig: 4 1s a view in side elevation.
5 represents the frame of the mill having bearings 6 and 7 in which the Vertical spindle 8 is mounted to rotate. The spindle projects through bearing 6 and is provided at its lower end with a gear wheel 9, which is designed to be geared up to a suitable motor for rotating it. The upper end of spindle 8 projects above the bearing 7 for the attachment of the vertical roll 10 which is in the shape of an inverted cone with a flange 11 at its lower end, the flange being substantially at right angles to its surface.
12 is a swinging lever approximately L- shape, its shorter member 12 being substantially vertical and itslonger member 12 outwardly and upwardly inclined as shown. This lever 12 is mounted at its lower end on the trunnion 13, within frame 5, and projects upwardly above the latter with its longer member 12 above the frame 5 and in a position to support the work, and is provided with the bearings 14 and 15 for the spindle 16 which latter is loosely mounted to turn in said bearings but is not positively driven. The spindle carriesthe conical roll 17 the top or working face of which is slightly convex, and is provided centrally or axially at its upper end with a shoulder 18 approximately at right angles to its upper working face and the roll is so located and the trunnion support of the frame 12 so positioned that when the frame 12 is swung inwardly, or toward roll 11, the upper perlpheral edge of shoulder 18 on roll 17 will pass under the inclined or inverted conical face of roll 10, and the conical or convex face of roll 17 will pass under the lower edge of shoulder 11 of roll 10, the said meeting faces of the two rolls being sufiicientl close to form a closed pass in which the b ank is rolled.
Rigidly secured to the frame 5 and projectlng horizontally at the side thereof opposite the lever 12, is the hydraulic cylinder 19 carrying the plunger 20, to the outer end of which the rods 21 are connected. These rods pass forwardly at opposite sides of the cylinder 19 and into frame 5 and are connected at their front ends to the pin 22 carried by the lever 12 at the elbow or bend in the latter, and operate to pull the lever with the roll 17 thereon toward roll 10, the weight of the .parts being sufficient to carry the said roll 17 in the opposite direction or away from the roll 10.
Mounted in the bearings 23 on the longer member 12 of the lever 12, is the work carrying roller 24 which is of a length sufficient to support the work at the commencement and throughout the rolling operation, the top surface of this roller 24 being located in the plane of the bottom of the pass between the two rolls 10 and 17, so that the major part of the work will be solidly supported throughout the diameter of the latter, thus taking the weight of the'outstanding part of the work off the rolls 10 and 17. y
This apparatus is designed for rolling rings, wheel tires billets from which rails ars to be rolled, etc., and when used for the making of wheel tires the roll 10 will be provided with a groove 10 to form the flange on the rim.
In starting the operation, the lever 12 is moved to its farthest position away from roll 10, and a blank is placed on roll 17 and roller 24, after which the lever is shifted b actuating plunger 20 to carry the roll 17 with the blank thereon toward the roll 10, the blank passing under the conical part of said roll 10 and against the shoulder 11. This ring shaped blank may be made in any approved way, but I prefer to construct it from a specially prepared ingot which is flattened or bloomed in a hydraulic press to the desired width, and then punched at its center to permit the bloom or blank to be properly placed on the roll 17. By prepar- 'ing the blank in this manner I avoid the necessity of discarding the top end of the i the rotating roll,
ingot, and remove all traces of piping and other defects which if permitted to remain. would eitherruin or seriously impair the integrity of the finished product. I prefer to flatten the blank or bloom so that its width willbe approximately the height of the pass between rolls l0 and 17. hence in rolling, the blank will be reduced in thickness and of course ex anded.
After t e blank or bloom has been so placed and the roll 1? moved to carry the work over against roll 10, the necessary pulling pressure is applied to lever 12 by means of the piston 20 and rods 21, and rotary movement imparted to roll 10. This rotation of the roll 10 feeds the circular blank between the rolls and rotates the roll 17. and the continuous movement of the endless blank between the said rolls, and the squeezing action of roll 17 against the blank expands the blank and gradually reduces its cross sectional area until the proper diameter of the ring has been reached.
If the article being rolled be a tire. the blank so rolled would be finished in the ordinary manner. If the blank be for a bloom for rolling into a rail road rail. the ring will be severed, straightened and rolled in the ordinary manner.
It is evident that many slight changes might be resorted to in the relative arrangement of parts shown and described without departing from the spirit and scope of my invention. hence I would have it understood that I. do not wish to confine myself to the exact construction and arrangement of parts shown and described. but
Having fully described my invention what I claim as new and desire to secure by Letters-Patent, is
1. In a mill for rolling endless blanks. the combination of a conical roll, means for rotating it, a swinging lever carrying blank supporting means, a conical roll also carried by the said lever and adapted to coact with one of said rolls being inverted, and means for moving the swinging lever to carry the roll thereon toward the rotating roll.
2. In a mill for rolling endless blanks. the combination of a conical roll, means for rotating same, a swinging lever carrying blank supporting means, a freely rotating conical roll also carried by the said lever and adapted to coact with said other roll. one of said rolls being inverted, and each having a shoulder substantially at right angles to its conical surface so that the two rolls form a rectangular pass. and means for moving the swinging lever to carry the roll thereon toward the other roll.
3. In a mill for rolling endless blanks, the combination of a frame, a vertical spindle journaled thereon, a conical roll on the upper end of the spindle, means for rotating the latter, a lever mounted to rock on said frame and carrying a freely rotating conical roll and also having a support for the work, one of said conical rolls being inverted and each having a substantially right angle shoulder at the smaller end of the cone. and hydraulic means for moving the nvinging lever to carry the roll thereon toward the other roll.
i. In a mill for rolling endless blanks, the combination of a frame, a vertical spindle journaled thereon, means for rotatin the spindle, a conical roll on the upper en%l of the spindle, a rocking lever journaled to said frame, a spindle mounted to rotate in bearings carried by said lever, a. conical roll on the upper end of said latter spindle. work carrying means also carried by said lever and located in a position to support the work in its passage to and from the rolls and means for moving the lever in a direction to carry the conical roll thereon toward the rotating roll on the frame.
5. In a mill for rolling endless blanks, the combination of a frame, a vertical spindle journaled thereon. an inverted conical roll m the upper end of the spindle, an approximately L-shaped lever journaled at its elbow to said frame. a spindle mounted to rotate in bearings carried by said lever. a conical roll secured to the upper end of said latter spindle and cooperating with the inverted conical roll. a roller carried by the upper member of said lever for supporting the ilank. and hydraulic means for moving the lever in a direction to carry the roll thereon toward the inverted conical roll.
i. In a mill for rolling endless blanks, the combination of a frame, a vertical spindle journaled in bearings in the latter. an inverted conical roll on the upper end of said spindle. an elbow shaped lever journaled at its lower end to said frame, a freely rotating spindle mounted in hearings on said lever. a conical roll on the upper end of said spindle. the said conical roll being located adjacent the bend in the lever, means carried by that part of the lever above the bend for supporting the endless blank, and hydraulic means for moving the lever in a direction to carry the roll thereon toward the roll on the rotating spindle.
ln testimony whereof I have signed this specification in the presence of two subscrilr ing witnesses.
